For many applications, silicas are not satisfactory alternatives to carbon blacks because of their relatively lower reinforcement levels. The fundamental problem is their surface chemistry, which is more polar and hydrate than
carbon blacks, and which cause them to be difficult to wet, disperse and interact with hydrocarbon rubbers. Numerous
methods have been carried out to improve the reactivity of silicas with the rubber phases. One such method is the
utilization of a silane-coupling agent to modify the surface of the silica. The modified silica provide chemically active
surfaces that can participate in vulcanization, providing coupling bonds between the silane and both the silica and
the rubber phases [4,5]. Those products show significant improvement in performance compared to their base materials.
